If we choose to live near convergent plate boundaries, we can build buildings that can resist earthquakes, and we can evacuate areas around volcanoes when they threaten to erupt. Yes, convergent boundaries are dangerous places to live, but with preparation and watchfulness, the danger can be lessened somewhat.
Nitrification, as stated above, is formally a two-step process; in the first step ammonia is oxidized to nitrite, and in the second step nitrite is oxidized to nitrate. Different microbes are responsible for each step in the marine environment.
Nitrification is important because plants can only use nitrogen in the nitrate form. However, when more ammonia is nitrified than plants can use, the unused nitrate will accumulate in the soil. Second, applying more nitrate fertilizer to the soil than a crop can use will build up high levels of nitrate.Finally, legume plants, such as alfalfa, can take nitrogen out of the air and put it into the ground through their root nodules.This process is called nitrogen fixation.itrification is important because plants can only use nitrogen in the nitrate form.
